calculate some thermodynamic properties of molten polymers including specific volume and isothermal compressibility (s.m. hoseini, physical chemistry & electrochemistry, 2 (2014) 56-65). this work extended that eos to predict the volumetric properties of some molten ethylene copolymers including ethylene/1-octene, ethylene/1-butene (xethylene equal to 0.8543 and 0.563), ethylene/propene. the ab...

the application of conductive coatings on ferritic stainless steel can decrease electrical conductivity. theaim of this research was to investigate the electrical conductivity of cobalt coated aisi 430 ferritic stainlesssteel by pack cementation technique. coated coupons were analyzed using scanning electron microscopy(sem). electrical conductivity of the coated substrates was measured as a fun...

We present the results of exact diagonalization calculations of the isolated and isothermal on-site static susceptibilities in the anisotropic extended Heisenberg model on a linear chain with periodic boundary conditions. Based on the ergodicity considerations we conclude that the isothermal susceptibility will diverge as T → 0 both in finite clusters and in the bulk system in two non-ergodic r...

We observe the formation of metastable AuGe phases without quenching, during strictly isothermal nucleation and growth of Ge nanowires, using video-rate lattice-resolved environmental transmission electron microscopy. We explain the unexpected formation of these phases through a novel pathway involving changes in composition rather than temperature. The metastable catalyst has important implica...

The non-isothermal continuous stirred tank reactor (CSTR) is a classical yet complex case study of nonlinear dynamical systems. Power-shaping control is a recent approach for the control of nonlinear systems based on the physics of the dynamical system and it rests on the formulation of the dynamics in the Brayton-Moser form. The Brayton-Moser formulation of the non-isothermal continuous stirre...
